I have a late-2013 13" rMBP and was getting terrific battery life on Mavericks: 10-12 hours. It's a little worse so far on Yosemite, but not a lot. Maybe an hour, hard to tell for sure because I don't run on battery all day. Yosemite does seem much snappier on my MBP, though. It just zips along.

I was getting terrible battery life on 11" 2014 MBA (~3 hours). I wiped it out and did clean install and now am at around 6.5 hours. Haven't put back on dropbox, etc. yet but am curious to see how that will affect things.

I have a 11" 2011 MBA and I'm pretty sure I'm getting like 3 hours. In fact I just saw the life drop from 1hr30min to 45min in less than 1 minute. Upgraded from Mavericks to Yosemite. Maybe I should do a clean install? I have drop box running and I think Chrome is the worst culprit right now but can't be sure.

I haven't had to ever plug it in this much and nothing significant has been done except web browsing.

I charged my MBA to full and powered it on. When I click on battery life, it show 16 hours remaining with 100% battery (obviously I won't actually get that, but still!) Looks like clean install did the trick for me.

Spotlight indexing still? Go to Activity Monitor, CPU tab and you can <see> what is using the CPU and therefore battery....

Don't think so... After a full charge estimate life was 4hrs 48min. That seems WAY too short.. (And in practice it sure feels like a hell of a lot shorter).. Really contemplating doing a fresh install now but I have tons of stuff on here.. Gahh.. annoying..
